I used to have the #1 parse for this fight until all these staffs started popping out. I still hold it as demo but that is kind of a joke haha. I did around 78k 3 weeks ago which was before I got a lot of upgrades. Maximizing your rings, keeping your dots up, and using DS on CD are essential. Also during Firestorm (if you are doing this on heroic) you can channel drain soul from quite a distance away while LoSing behind the meteor. For normal mode you have lots of time to off dot the Hatchlings as she flies through the middle of the room. Take advantage of that!
